Prompts for discussion:

There is a lot to be said about Kakeya sets that we did not get into at all due to time constraints. I was hoping to be able to locate an interactive construction of the Perron tree to share here, but I couldn’t find one. For now, the miniature has a nice description of it, as does Wikipedia.

Here’s a discussion potentially of interest, about explicit constructions of Kakeya sets over finite fields.
